FLUlD-EJECTOR.

' SPECIFICATION forming part of Letters Patent No. 346,792, dated August3, 1886.

Application filed May 7. 1886.- SerialNo. 201,421. (No model.)

To all whom, it may concern:

Be it known that I, CHARLES WHITE, a citizen of the United States,residing at Baltimore, in the State of Maryland, have invented certainnew and useful Improvements in Fluid-Ejectors, of which the following isa specification, reference being had therein to the accompanyingdrawings.

My invention relates to improvements in valve-operating devices forejcctors, which is so arranged that the Weight of a column of fluidoperates the cut-oft valve between the ejector and the pressure-pipe, asillustrated in the accompanying drawings, in which- Figure 1 is avertical sectional view of a Well and the ejecting devices placedtherein; Fig. 2, a top view of the diaphragm and its casing.

Similar letters refer to similar parts throughout the several views.

The letter A designates the pressure-pipe, which contains fluid underpressure, connected to the ejector B O, the discharge-pipe, which isalso connected to the ejector, and which extends to the desireddischarging place. The ejector B, as herein shown, is arranged with theingress-port a connected with the pressurepipe A, and leads to theorifice a", with the cutoff valve D placed therein. \Vhen the valve D isopened, the pressurewater passes from the orifice a across the passage2) into the egress-port c, which is located concentric with the orifice,thereby forming a vacuum in the passage 1), which permits theatmospheric pressure to act on the static water in the well E, andforces it into the passage, from which it is discharged by and with thejet from the orifice a, by way of the discharge-pipe G, from the well.

To prevent any fluid from passing into the Well E by way of the passageb, a valve is arranged at its opening to prevent the same, at-

the same time permitting it to take in the fluid. The valve consists ofa casing, cl, inclosing the opening of the passage, and provided witha'disk, d, that will seat itself against the casing and prevent any backaction, but as soon as a vacuum is formed in the ejector it is therebydrawn up against the casing of the passage 12 and there held, thuspressurefluid will hold it seated over the orifice a, or when opened thesame pressure will hold it so by seating it against the cap h. From thehead f projects the stem 2', which extends through the cap h, and isconnected to the diaphragm F by the circular plates Z, riveted to thestem m, and the latter connected to the stem 13 by suitable means.

In ejectors that are used to elevate static water, that accumulatesslowly, it is desirable that they should work only at intervals, and,when the said water has been ejected, to cease acting until a sufficientquantity has again accumulated. To accomplish this I arrange incombination with the ejectorB a diaphragm, F, that is secured perfectlyairtight at its periphery to the outer portion of a concave disk, G,connected to the ejector at H, which permits the central portion to bedepressed by the weight of the fluid column, Which,when its height issufficient to exert pressure enough on the diaphragm to overcome thatexerted on the piston-head f, it withdraws the same and puts the ejectorin operation, which continues to operate until the static water hasnearly all been ejected from the well, or until the weight of the fluidcolumn has lessened sufliciently to permit the air compressed betweenthe diaphragm F and the disk G, to overcome the pressure in the port a,then exerted on the piston-head to hold it open, which again seats thepiston-head f over the orifice a, and stops the operation. By thisdevice the pressure-water is suddenly applied to the ejector andlikewise cut off, and the water permitted to accumulate in the Well insufficient quantity before the ejector is put in op eration, and toremain so until all or nearly all of it has been ejected, when it ceasesto act, thus resulting in an automatic device to elevate fluid by asimilar fluid under pressure, which is very desirous for drainingcollars and like purposes.

IOO

Having described my invention, what I claim is- 1. The combination ofthe pressure-pipe A, the discharge-pipe O, the ejector B, connected tothe said pipes, the cut-off valve D, and the diaphragm F, attached tothe cut-off valve I), and arranged to be operated by the weight of thestatic water in the well, by which, when the well has accumulatedsufficient water, the valve is opened by the weight of the said staticwater and the ejector put in operation thereby.

2. In combination with the ejector l3 and a cut-off valve, the diaphragmF, connected to the cut-off valve and arranged to be operated by theweight of the static water in the well, by which the ejector is put inoperation by the weight of the said water.

3. The combination of the ejector 13, the

20 cut-off valve 1), the diaphragm F, arranged to operate the valve D,and the eoneaved disk supporting the diaphragm and forming an air-spacebetween the diaphragm and the disk, as set forth.

4. In combination with the ejector B, the cutoff valve D and thediaphragm arranged upon a closed air-chamber to open the valve by theweight of a column of water, and close the same by the action ofcompressed air, as set forth.

5. The combination of the ejector B, the cut-off valve 1), the diaphragmF, and the disk G, for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.
